Substitute Part Grouping Explanation

Substitution eligibility for the 91J20RE is determined by strict equivalence across the following parameters:

• Resistance value: 20 Ohms
• Tolerance: ±5%
• Power rating: 1.5W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±30ppm/°C
• Physical dimensions: 0.142" Dia x 0.453" L (3.60mm x 11.50mm)
• Termination count: 2

The substitute part 91J20R meets all electrical and mechanical requirements for direct substitution. Differences in RoHS compliance status do not affect functional equivalence but may impact application suitability based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 91J20RE and 91J20R are Active status components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

• 91J20RE: Select this part for applications requiring RoHS3 compliance or where regulatory documentation mandates compliant components.
• 91J20R: Select this part where RoHS compliance is not a requirement and inventory availability is the primary consideration.

Both parts are suitable for identical circuit applications given their matching resistance, tolerance, power rating, and physical characteristics.

Frequently Asked Questions (FAQ)

Q: Can 91J20R be used as a direct replacement for 91J20RE?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (20 Ohms), tolerance (±5%), power rating (1.5W), composition (wirewound), package type (axial), and physical dimensions (0.142" Dia x 0.453" L). The primary difference is RoHS compliance status.

Q: What is the significance of the RoHS compliance difference?

A: RoHS3 compliance (91J20RE) is required for applications subject to European Union Restriction of Hazardous Substances regulations or equivalent regional requirements. RoHS non-compliant parts (91J20R) may be used in applications without such regulatory constraints.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical axial package dimensions of 0.142" Dia x 0.453" L (3.60mm x 11.50mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both parts have a temperature coefficient of ±30ppm/°C, ensuring equivalent thermal performance across operating conditions.

Q: Can these parts be used interchangeably in production?

A: Interchangeability depends on regulatory requirements. If RoHS3 compliance is mandated, use 91J20RE. If no compliance requirement exists, either part may be used based on availability.
